  When the conventional handrail device is attached to the folded staircase, as shown in FIG. 7, the hand attached to the wall surface 2A facing the landing of the partition wall 2 between the staircase and the staircase at the switching portion at the landing. The sliding portion 4A is provided in the horizontal direction, and is bent toward the end side of the horizontal handrail portion 4A in the direction along the wall surface 2B facing the stairs of the partition wall 2 and in the direction along the inclination angle of the stairs. Is done.

The handrail 4 in the switching portion at the landing is covered with a cover after the core material is bent as described above, but the core material has an opening of a groove formed in the core material. Since the bending process described above is performed so as to face downward, there is a problem that this process is quite difficult.
The cover is covered with a core material that is bent by softening the cover with heat from a burner or the like, but the operation of covering the cover with the core material that has been bent is very difficult and has poor workability. There is a problem.

  Therefore, in view of the above problems, the present invention provides a handrail device that can easily construct a handrail from a horizontal direction to an inclined direction that is orthogonal to the horizontal direction and that is inclined with respect to the vertical direction. The purpose is to do.

The technical means taken by the present invention in order to solve the technical problem includes a core member attached to a mounting bracket attached and fixed to a mounting surface, a cover covering the core member, and the mounting bracket. A handrail in which a downwardly open groove is formed in the core material and the cover along the handrail longitudinal direction so that the core material and the cover can be attached at any position in the handrail longitudinal direction,
A corner joint that connects one handrail arranged horizontally and another handrail arranged in a direction orthogonal to the longitudinal direction of the one handrail,
The corner joint can be fitted to the end side of the one handrail so that the other handrail can be attached to the horizontal direction so that the angle of the other handrail can be freely adjusted around the longitudinal axis of the one handrail. It is said that it is said.

The corner joint may be fitted on the end side of the other handrail so that it cannot rotate relative to the longitudinal axis of the other handrail.
Further, the corner joint includes a joint body formed in a pipe shape bent at 90 °, and one end side and the other end side in the axial direction of the joint body are fitted to a handrail cover. In the center side of the fitting tube portion that is fitted on the cover of the other handrail, the longitudinal axis of the other handrail from the longitudinal end to the groove of the core material of the other handrail It is preferable to provide an insertion portion that is inserted so as not to be relatively rotatable around.

Moreover, it is good for the said insertion part of the said corner joint to protrude from the fitting cylinder part externally fitted to the cover of another handrail.
Further, the mounting bracket has a mounted portion that is fixedly mounted on the mounting surface, and a handrail mounting portion that is mounted on the core.
The handrail mounting portion may be connected to the mounted portion so that the angle thereof can be adjusted with respect to the horizontal direction.

  According to the present invention, when constructing the handrail from the horizontal direction to the inclined direction perpendicular to the horizontal direction and inclined with respect to the vertical direction, there is no need to bend the core material of the handrail. The construction can be easily performed, and it is not necessary to perform a work of covering the bent core material with a cover as in the prior art.

As shown in FIGS. 5 and 6, the mounting brackets 3A and 3B support the handrail 4, and the attached portion 23 attached to the wall surfaces 2A and 2B by bolts and the handrail 4 are attached. A handrail mounting portion 24, a connecting portion 25 that connects the mounted portion 23 and the handrail mounting portion 24, and a bracket cover 26 that covers the mounted portion 23.

  The mounting brackets 3A and 3B are variable-angle mounting brackets 3A (the handrail mounting portion 24 is adjustable in angle around the rotation axis X in a direction perpendicular to the wall surface 2B (the mounting surface of the mounted portion 23)). There are a first mounting bracket 3A) and an angle invariant mounting bracket 3B (referred to as a second mounting bracket 3B) in which the handrail mounting portion 24 is fixed to the connecting portion 25.

The connecting portion 25 is integrally extended from the upper portion of the attached portion 23, and has a base attaching portion 27 on the side opposite to the connection portion with the attached portion 23.
The handrail mounting portion 24 of the first mounting bracket 3A includes a base portion 28, a core material receiving portion 29 extending upward from the base portion 28, and a longitudinal direction A of the handrail 4 from the lower portion of the core material receiving portion 29. It has a pair of support part 30 extended on both sides, and the fixing member 32 which is arrange | positioned at the upper surface side of each support part 30, and was attached to the support part 30 via the fixing screw 31.

  The base portion 28 of the handrail attachment portion 24 is overlapped with the back surface side of the base attachment portion 27 of the connecting portion 25, and the angle fixing screw that penetrates the base attachment portion 27 and the base portion 28 from the front surface side of the base attachment portion 27. 33 and the angle fixing nut 34 screwed to the angle fixing screw 33 are attached to the base mounting portion 27, and the axis of the angle fixing screw 33 is the rotation axis X.

When the fastening of the angle fixing screw 33 and the angle fixing nut 34 is loosened, the rotation of the base portion 28 about the rotation axis X is allowed, and when the angle fixing screw 33 is tightened, the base portion 28 cannot turn to the base mounting portion 27. Fixed to.
Therefore, the handrail 4 can be mounted at a desired inclination angle with respect to the horizontal by the first mounting bracket 3A.

The inner diameter of the fitting tube portion 42 and the outer diameter of the handrail 4 are formed to have substantially the same diameter, and when the fitting tube portion 42 is fitted onto the cover 7 of the handrail 4, the fitting tube portion 42. With respect to the relationship between the portion 42 and the cover 7 of the handrail 4, these can be rotated relative to each other about the axis in the handrail longitudinal direction A.
Further, the thickness of the fitting tube portion 42 is such that a contact surface 44 is formed so that the end surface in the longitudinal direction of the handrail 4 contacts the end portion on the inner surface side of the fitting tube portion 42. It is formed thinner than the thickness of the portion 43.

Further, the center of each fitting tube portion 42 is arranged in the axial direction, and when the fitting tube portion 42 of the joint body 41 is externally fitted to the cover 7 of the handrail 4, the core of the handrail 4. A rod-like insertion part 45 is inserted into the groove 14 of the material 6 from the end in the handrail longitudinal direction A.
Each insertion part 45 protrudes from each fitting cylinder part 42.
Each insertion part 45 is integrally extended from the rod-shaped support part 46 provided concentrically with the corresponding insertion part 45 in the corner part 43 of the joint main body 41.

The two support portions 46 are connected to each other at the back portion in the corner portion 43 and are connected to a wall portion constituting the corner portion 43.
A plurality of ribs 47 are provided between the support portions 46 and the inner surface of the corner portion 43, and the support portions 46 are connected to the inner surface of the corner portion 43 by the ribs 47.
